Although he is widely regarded as the 'founding father' of realism in International Relations, this book argues that Hans J. Morgenthau's legal background has largely been neglected in discussions of his place in the 'canon' of IR theory. Morgenthau was a legal scholar of German-Jewish origins who arrived in the United States in 1938. He went on to become a distinguished professor of Political Science and a prominent commentator on international affairs. Rather than locate Morgenthau's intellectual heritage in the German tradition of 'Realpolitik', this book demonstrates how many of his central ideas and concepts stem from European and American legal debates of the 1920s and 1930s. This is an ambitious attempt to recast the debate on Morgenthau and will appeal to IR scholars interested in the history of realism as well as international lawyers engaged in debates regarding the relationship between law and politics, and the history of International Law.

Realism remains the most important and controversial vision of international politics. But what does it mean to be a realist? This collection addresses this key question by returning to the thinking of perhaps the most influential realist of modern times: Hans J. Morgenthau. In analyses of issues ranging from political philosophy, to international law, to the impact of nuclear weapons and the challenges of American foreign policy, the authors demonstrate that Morgenthau's thinking exemplifies a rich realist tradition that is often lacking in contemporary analyses of international relations and foreign policy. At a time when realism is once again at the centre of both scholarly and political debates, this book shows that the legacy of classical realism can enrich our understanding of world politics and contribute to its future direction.

This is the first comprehensive study of how different ethical traditions deal with the central moral problems of international affairs. Using the organizing concept of a tradition, it shows that ethics offers many different languages for moral debate rather than a set of unified doctrines. Each chapter describes the central concepts, premises, vocabulary, and history of a particular tradition and explains how that tradition has dealt with a set of recurring ethical issues in international relations. Such issues include national self-determination, the use of force in armed intervention or nuclear deterrence, and global distributive justice.

Is it possible to preserve national security through ethical policies? Richard Ned Lebow seeks to show that ethics are actually essential to the national interest. Recapturing the wisdom of classical realism through a close reading of the texts of Thucydides, Clausewitz and Hans Morgenthau, Lebow argues that, unlike many modern realists, classic realists saw close links between domestic and international politics, and between interests and ethics. Lebow uses this analysis to offer a powerful critique of post-Cold War American foreign policy. He also develops an ontological foundation for ethics and makes the case for an alternate ontology for social science based on Greek tragedy s understanding of life and politics. This is a topical and accessible book, written by a leading scholar in the field.
